any ideas why it wont come out?i removed the cap and removed the 12mm bolt that holds it in and tried lifting it out ... nothin cant budge the thing. i noticed the the housing is flopping around(like its broken on the bottom)and having a hard time getting it to time correct,so i decieded to remove and swap it with a known good 1.this is the last item to be done and it,s fighting me the whole way! could use some advice. thanx joe g
